Referring to th drawing for a full detailed description of tneinv'e'ntion, the improvedstrip trimming and fe ding attachment genera ily-in dica'ted at lliis shown i-n Fig. '1 as bein applied to a tabulating machine I l of known construction having a cylindrical "platen i=2 mounted for rota tion "on the tabulatcr. T p bars (not shown) are mounted in knowninanner on the tabulator for impies'singthe writtei1eharatters upontiie paper supported on the platen --surface, such as the record stripes of the lon-g'continuous traveler type, as shown. An inking ribbon "is used for inscribing the characters on the top or original reooidstripbeing mounted on supplyspecie in the usual marinenpn'e of-which is Shawn-at "l3. Frame er I end plates 1 4 are mounted upon the tabulater ad acent to opposite ends or the-platen l2 rcr supporting eertain operative parts, and zit-transverse shatter bar =|5-ls attached 'piihanently' in ention tn the tabulatcri supporting arms [-6 are attached in position'oh thetabulatoi'; extending upwardly and restate-rely and being When the improved strip trimming and feeding attachment is applied to the tabulator the supply of record strips S is ordinarily carried by a support or stand I1 having a lower shelf [8 upon which the supply of strips rests. The supply shown is in the form of a supply pack l-9 in which the strips S are zigzag folded to form a compact package. The upper shelf 20 of the supply stand is arranged to receive the strips S as they emerge from the writing machine after inscription thereof. These inscribed strips will be refolded again on the shelf 20 in the form of a zigzag folded pack 2|.

While strip assemblies of different forms or single strips may be utilized, for illustrative purposes a record strip assembly S is shown having two or more record strips of the long continuous traveler type in superposed relation, each strip being preferably provided with blank forms S in longitudinal series therealong and having transverse lines or spaces in which the inscriptions are to be received. Each of the record strips is ordinarily provided with transverse weakened severance lines S dividing it into form sheets, and a longitudinal feed band S separated from the body of the strip by weakened severance lines S formed by perforating or slitting the strips or by other known means. Each of the feed bands S has a series of pin feed apertures S the apertures of the different bands being in respective depthwise alignment for the reception of the feed pins. In some cases the longitudinal weakened lines 5* may be omitted. A long continuous carbon strip is positioned in transfer relation between each two adjacent record strips S so as to transfer the inscriptions to the lower or copy record strips. The carbon strips C may have longitudinal marginal portions interposed between the feed bands S and be similarly provided with feed apertures, or the adjacent edges of the carbons may terminate inside of the feed bands. The assembly strips are usually connected together at various points along the assembly by suitable securing devices, or the record strips may be connected together by longitudinal marginal folds as in the well known fanfold structure.

The improved strip trimming and feeding attachment has a unitary supporting frame so that the complete attachment can be quickly and easily installed as a unit upon the writing machine and can be similarly removed therefrom. This supporting frame includes end brackets or plates 22 and transverse connecting or tie rods 23 to the opposite ends of which the end plates 22 are connected. The lower edges or extensions of the end plates 22 are formed with supporting pockets or seats 24 for receiving the transverse rod I of the writin machine for supporting the attachment in operative position. Additional supports for the attachment are provided by the upwardly and rearwardly extending supporting arms 16 having at their upper ends attaching devices or bolts 25 that are received in apertures in the end brackets 22 and provided with threaded wing nuts 26 for securing the attachment firmly in operative position. The attachment It can thus be quickly and easily installed in operative position upon the writing machine by placing the supporting seats 24 upon the supporting rod l5 and tightening the attaching bolts 25 in attaching position.

The main drive shaft 21 for the trimming and feeding mechanism is rotatably mounted in bearings 28 that are detachably supported in operative position in seats 29 formed in the edge portions of the end plates 22. These bearings 28 are clamped or supported in position by clamping levers 30 pivoted at 31 to the end plates 22 and each having a projection or overhanging lip 32 adapted to engage with the bearing periphery when the-clamping lever is forced downwardly into clamping position as shown in Fig. '7. When the levers are in their holding positions the lips 32 function to hold the levers in clamping position and to prevent accidental release thereof. However, the clamping levers can be easily moved to releasing position by exertin upward pressure thereon, whereupon the drive shaft 21 with attached parts can be lifted as a unit from the supporting seats 29.

The strip feeding wheel 33 is mounted upon the drive shaft 21 for rotation therewith but may be slidably adjusted along the shaft. This feed wheel is provided with a series of feed pins 34 arranged in equally spaced relation peripherally of the wheel so as to engage in feeding relation in the feed apertures of the strips S. Mounted also upon the shaft 21 is a sleeve 35 extending into the hub 35 of the feed wheel and firmly attached to the latter by any appropriate means, such as by means of a set screw or by shrinking the hub into tightly contacting relation with the sleeve. The sleeve has an extension 35' at one side of the feed wheel threaded to receive a threaded adjusting nut 31. An anchoring collar 33 is mounted upon the sleeve 35 just insideof the adjusting nut 31, forming an abutment for the latter and having a peripheral groove 39 in which an anchoring plate 40 is slidably received and firmly attached in stationary position upon the frame. A coiled compression spring 4| is interposed between the stationary collar 38 and the adjacent face of the feed wheel 33. The sleeve 35 extends through a centrally disposed aperture in the collar 38 and the collar is constrained for rotation with the sleeve by means of a key 42 seated at its inner surface in a concave depression 43 in the sleeve, and seated at its outer surface in a groove or keyway 44 in the collar. In this manner the collar is constrained for rotation with the sleeve but the sleeve may slide longitudinally in either direction through the collar. The feed wheel 33 and sleeve 35 are anchored for rotation with the feed shaft 21 by means of a key 45 pinned in a seat or slot to the hub 36 of the feed wheel and extending through a slot in the sleeve into an elongated groove or keyway 45 in the feed shaft.

Thus the feed wheel with assembled parts is constrained for rotation with the feed shaft 21 but may be adjusted longitudinally thereof, that is transversely of the path of strip feed. Adjustments of the pin wheel transversely of the strip path are effected by turning the adjusting nut 31 in one direction or another, and the wheel is retained in adjusted position by means of detents or pins 41 mounted in the nut and projecting at their inner end portions into seats or depressions in the adjacent abutting surface of the collar 38.

Adjacent to the series of pins 34 the feed wheel 33 is formed with a peripheral groove 48 and inside of this groove is an annular support 49 for the strips. The strips are thus supported on one side of the groove 48 by the wheel and pins and on the other side thereof by the annular support 49. The purpose and function of this arrangement are set forth below.

Strip guiding means is provided for guiding the strips: from the supply 19 to the platen, including a guideplate 50 attached by means of lugs or brackets 50' to the tie rods 23. Also, a guide 'plate. overlies the plate '50 and is mounted for upward swinging movement by means-of supporting arms 52 upon one of the transverse tie rods =23Jandrests by gravity upon the upper. surface of the advancing strips. The guide plate 50 is curved to guide the strips in a smooth even path to the :rear side of the platen 12. Also, transverse guide bars 53 and a transverse guide plate *5! are mounted upon the frame for guiding the strips in theirm'ovement away from theplatento 'the fe'ed wheel 33. The guides 53.and 54 are positioned inwardly-to increase'the 'arc of contact of the strips with the platen I 2 and also to increase "the arc of contact with the feeding periphery of the feed wheel.

For Zguiding. and holding the strips in feeding engagement with the=feecl pins and the periphery of the feed wheel-there is. a guide plate 55 piv- "oted at '55 at-a point spaced from the shaft 21 to-a supporting bracket 5! attached to one'of the longitudinal strip guiding end flanges 58 of the guide '50. The guideplate' 55 is curved .to conform to the periphery of the feed wheel and is provided with an elongated slot 59 in which the feedqains run. 'A-positioning and retaining leaf spring [it] is attached tothe guide plate 55 engaging with a transverse retaining roller 6| to therearward of 'the'pivot56 tensioned to urge the "guideplate toward the'feed wheel in strip guiding relation. The springBll is provided with a pocket or stop formation '62 adapted to engage with the roller -6 I carried by the-bracket 51 when the guide plateis lifted on its pivot away from the feed wheel so as to hold it in raisedposition when the strips-are being placedin operative'position upon the feedpins. adjusting screw 63 is threaded to'an'arm or'support of the bracket 51, having its upper free end engaging with thelower surface 'of-the:guide plate 55 at the right of the pivot 56 inFigQS, wherebytheposition of the guide plate maybe adjusted and maintained in adjusted position with reference to the periphery of the feed wheel. I

As best seen-in Fig. 2, there is a stripping plate M secured in position to the bracket 51 and havingits'freeend adjacent to the periphery of the feed wheel near the point where the record strips 1:

emerge frornengagement with the wheel and feed pins. This-plate functions as a stripper or separator to separate the record strips from engagement with the feed pins during the strip feeding action. -A strip'guiding'and supporting plate- 65-conductsthe record strips emerging from the-feedwheel-into position to be refolded on the shelf 20 into the zigzag folded pack 2|.

; Also, mounted-upon-thepivoted guide-plate and secured thereto by screws 66' is a feed band separatoror slitter 66 that is adapted to sever or separate the feed bands S from the strips as soon as they have-performed their strip feeding function. The guide plate 55 with its mountings thus provides-a-movab1e carrier'0r support for the stripseparator which is movable with the guide plate ;into and away from'its operative position.

As bestshown in'Fig. 6, the strip separator 66 includes-a separator element 61 shown in the form of .a blade hav-ing a sharp cutting edge directedagainst the advancingrecordstripsso as to cut or slit the feed bands from the main bodies of the strips. This slitter blade is received in a supporting slot or pocket and clamped in appropriately i adjusted position by a set screw '68.

whe lowerrend o'f-the slitter bl'aderuns in the e= r iphera'l groove 48 of the feed wheel and its outting-edge isinclin-ed forwardlyagainst-the moving strips so' that the strips are directed against the cuttingedge with a wiping action tofacilitate the severance. :Also, at thepointthat the severance takes' place the strips aresupported and steadied at the opposite sides of the peripheral groove-"d8 by the-surface of the feed wheel at the bases of the feed :pins and by-the annular support '19.: The-pinsaiso assist in supporting and steadyin the strips during the trimming action of the blade. By these means the severance of the feed 'bands 'is facilitatedand a clean smooth severed strip edge isassur'ed; Althoug'hthe rec 0rd strips. are shown as having longitudinal weakened severance lines along the feed bands S for somepurposes where a'sharpedged slitter blade is u'sed these weakened lines maybe 'omit ted so that the slitting action occurs along unweakenedparts of the strips. Incases where the separator 61 has'alblunt-or-rounded severing edge the weakened lines S are'n'eeded.

Duringrinitial threading. ofthe record strip assembly into feedingz-position, the strips are led forwardlyfrom. the supply 19' over the-Iguide'plate 5B and beneath thegravityguide'plate 5| which may be raised for thispurpose. The strips are then advanced downwardly around the platen I 2 and upwardly over the front surface-thereof, and into guiding relation withthe guide rods 53 and guide plate 54.. If: it is'desired to'write on the forward end portions ofthe strips before they reach-feeding engagement with the feed wheel 33-,-,the preliminary strip feed may b'eeffected by rotating the platen 12 by means'ofthe knob or handle !2. Pressure -roll's=69 mounted upon a suitable carrier 10 with a-manual control 1| are providedforpressing the strips against the platen during this initial feeding. As soon as the for wardends of the strips reach the feed wheel 33 the feed pins areengaged with the apertures in the strips and the-guide plate 55 moved into guiding relation with the strips. Subsequent feeding of-thestrips will be-by means of the feed wheel 33,the pressure rollsGS being released.

'Asshown in Fig. -1,--the-main-drive shaft 21for the feeding mechanism iscoupled by driving connections including -a =driving shaft 12 with the rotary platen-l2 of the writing machine. These driving connections are diagrammatically shown and-include the driving shaft '12 connected at its lower end with abeVelled toothed gear meshing with a similar. gear on the platen shaft and mounted in the housing 13. At its upper end the drive shaft is connected to another toothed bevelled gear meshing with-a similar gear on the main drive shaft 21,. these bevelled gears being mounted in thqhousing l4. A.micr0matic adjustment controlled t hrough a knurled head 15 may bemounted in the housing 14 for adjusting thefeed shaft '21 angularly through small increments independently of movement of the platen. The drive shaft "is connected to the bevelled gear in the housing I3 by means of. a coupling 16.

After the strips havebeen engaged with the pins of'the feed wheel '33; strip feed is continued through action of this. feed wheel which is driven step by step by'the drivingconnections with the platen. V The strips, at points spaced laterally from the feed wheel, are supported in line with the feed wheelperiphery by means of circular supporting disks 11 mounted upon thedrive shaft 21. As the strips. are advanced-by: theefeed wheel strips b action of the feed band separator 56, the severed bands S being conducted to one side by a guide rod I8. During the slitting or cutting action, the strips are supported and steadied by engagement with the feed pins and also by means of the periphery of the feed wheel at the bases of the pins, and by the annular support 49 as described. Clean, even severance is thus assured, and tearin and mutilation of the strips avoided. The slitting action occurs substantially at the point at which the feed pins have completed their strip feeding action.

The trimming and feeding mechanism can be adjusted laterally upon the supporting rods 23 and is maintained in adjusted position by means of pivoted clamping levers 19 having eccentric clamping surfaces engaging with the rods 23.
